Linux = HP-UX Tools

[John Meissner]

at the company I work at we use SuSE Enterprise Linux 7 & 8 because SAP has certified them. They have LVM and I would recomment Reiser FS instead of ext3. The admin tools for this distribution are easy to use and the distribution is easy to install. I believe you can also install LVM on Red Hat (my prefered distribution) but I honestly havn't tried.

for the bootable image - you might want to look into Red Hat's kickstart utility.

I am not familiar wit APA so I can't answer that part for you ... sorry.
I hope this helped

1. lvm was ported to Linux. I did a thread months ago and the actual users reported that lvm was not quite ready for prime time. It was ported by reverse engineering. The default linux filesystem is a journaled filesystem.

2. Ignite for Linux. No. I boot my machine, which has an Intel NIC card, with a special diskette. It connects to an NT Server and I use Norton Ghost to create an image. Another special diskette does an automatic boot, connect and restore of the image. If you have a cd writer on the box, Norton Ghost can write the system to a bootable cd set.

3. Don't know.

Good Luck.

Bakcground. I'm running a web hosting business on a set of machines which now currently run Red Hat 7.3. A gradual upgrade is planned to Red Hat 9 when I think its stable.

I have a home made failover environment where the secondary machine detects the total loss of the main machine, it attempts to take over service. It has a nightly data transfer to keep it up to date. The system has worked in test, and once did take over production when someone managed to fill up the main systems keyboard to the brim with water(my wife, long story).

Relying on SUSE lvm IS ready for production use. Personally I did never experience any problems with it...

Decide for yourself :-)

That's great news Chris.

I know HP's thoubs about ditching lvm were stopped after wide use and acceptance began in the Linux commmunity.

Can't wait to start playing with it. It should be interesting if you can create and change mirror assignments with lvextend command like in HP-UX.

If I can use the lv commands as I do in HP-UX it will make me a much more competant Linux Admin.

Here is a link to my thread on lvm, which is several months old.

FYI
Linux has a software mirroring.
But it is NOT in the LVM.
It is called MD(Multiple Device).

Other LVM commands are almost same as HP-UX's.
You can use LVM snap shot for backup purpose.... Enjoy!

Sorry about the delayed point assignments.

I didn't know this thread was still being replied too.

Well it's been a long time since I actually started the thread. And boy have I learned more about SuSE and Linux in general.

I do use Mondo an all my production Linux Boxes and it actually does work a lot like Ignite. The originally problem I had was simply needed to upgrade some of the programs that mondo uses. ( This is when I learned what an rpm was and how to use it. = swinstall/patches. )

I have been able to use LVM on Linux in some testing.

We have been in production with Linux servers for over a year now. We are trying to get an Oracle Rack test going. ( Me and the primary DBA )

Really interested in how the Clustered FileSystem really works and how two different systems and take ownership of the drives/data without causing FileSystem/Data corruption!

I work in a SAP shop and this could be a great advancement to have two Database Servers "ACTIVE" in a cluster.

If what I read works it will be much better then the Active/Passive clusters that most databases use today for failover.

Since the thread started things have changed.

Updated answers interleaved with your original question.

I need to know what software is available for Linux (SuSe?) that will give the same functionality as my HP-UX servers.

1. LVM/On-Line JFS - must be able to extend any filesystem on-line. I understand that the boot filesystem or /stand my be the exception to this but this is ok.

LVM yes, without mirror/ux Online JFS no, Linux uses its own filesystem and though I don't know how to do it, you can extend a filesytem hot in Linux with LVM or Linux tools without any add in products.


2. Ignite for Linux? I need a bootable image for DR reasons.

No. Though we just found out about Service Guard for Linux. I have heard unofficial rumors about some kind of port, but nobody will talk on the record. Its a tough port, because Linux does have a totally different method of creating boot information on disks.

3. Dual-Home/APA - We use APA on our HP-UX machines any dual home functionality will do.

This apparently does exist in the Linux world, its open source and not built into the distributions.

Hello!

As i understand that you migrate from hpux to linux.

The oracle work good on the hpux but for today
linux give also good work for oracle on.
Well SAP also run in the world on linux grow more and more.

HP made develop of service guard for linux for about 1-2 years.
And as i know people alrady use it.
